Answer this question truthfully
### Question: What to expect if I have Acoustic neuroma  (Outlook/Prognosis)?
### Response: Acoustic neuromas are not malignant and do not metastasis (spread) to other Organs. However, some untreated or even relapsed tumor can grow rapidly and invade surrounding structure such as nerves, ear and brain tissue, especially brain stem which is life-treating. Even after adequate treatment by surgery or radiation some complications such as hearing loss and balance problems caused by tumor may be persistent. The least permanent complication are seen when the tumor discovered in its primary stages when its really small therefore its more likely to preserve hearing.
